crescendo

A crescendo is a gradual increase in volume, indicated in notation by a long hairpin opening to the right (< shape) or by the abbreviation cresc. It is one of the most fundamental dynamic markings and appears in virtually every genre of Western music. A well-executed crescendo builds tension and excitement, drawing the listener toward a climax. Rossini was famous for his crescendos — long, orchestral build-ups that became his signature. The Rossini crescendo typically combines increasing volume with accelerating rhythm and the gradual addition of instruments, creating an irresistible sense of momentum.
